We don’t know them all yet, but we do know where one of the 2019 Silverado engines will call home. On Wednesday, General Motors announced the Flint Engine plant will build the half-ton pickup’s new 3.0-liter Duramax diesel engine.

The announcement follows a 2015 investment in the GM Flint Engine plant, officially known as GM Flint Engine Operations, for a new engine line. Then, GM invested $263 million to tool the plant to produce the the 3.0-liter Duramax diesel engine. When the Duramax inline-six enters production, it will join the 1.4- and 1.5-liter four-cylinder engines currently in production at the plant for the Cruze, Equinox and Volt.

Chevrolet did not reveal the 3.0-liter Duramax diesel engine’s major specifications at the 2019 Chevrolet Silverado reveal this past Saturday, but GM product chief, Mark Reuss, claimed “[GM will] have the best-performing diesel in this segment.” If Reuss is a man of word, and we’re sure he is, that will mean the Duramax inline-six will make more 250 horsepower and 440 pound-feet of torque, Ford’s Powerstroke V6 performance figures.

Aside from the 3.0-liter Duramax diesel engine, the 2019 Silverado engines lineup will also include updated 5.3-liter V8 and 6.2-liter V8 motors. Both engines will boast Dynamic Fuel Management, which can shut off up to seven cylinders to further improve fuel economy. In addition, we may even see a four-cylinder-powered Silverado – though GM has yet to announce such an engine, for the time being.
